I've painted plastic, metal, fabric, paper and resin with minimal issues. I found that painting over fabric is particularly successful, and white is best. I was glad that I read the reviews that indicated that while this works well- it is very thin. On occasion, you do need a few coats to really pop- particularly if the object isn't stark white. This didn't show up on anything I painted in normal light- and is very much invisible until revealed by blacklight. This is exactly the answer to what I was looking for, for personal projects. I would buy again. Review: Awesome - It works very well. Completely clear without a blacklight. No issues with skin. Used it on face, neck and arms. Lasted all night of dancing amd probably more. ## Features - Invisible in regular light, glows bright blue in blacklight.

The exact appearance would depend on how absorbent the fabric is. **Q: I live in a high crime town,i have lost 5 tables from the front porch,looking for a invisable long lasting ink/marking method so if cops can identify** A: If you mark the underside of the table so that it is not exposed to sunlight or rain, it should work fine. **Q: Can you use if in a fountain pen?** A: Would not be ideal for this purpose. Fountain pen ink is typically water based. Our inks are alcohol based and much thinner than a water based ink. They can work well with calligraphy pens in some cases, but an alcohol based ink would not mesh well with the internal parts of a fountain pen. **Q: What wavelength (nm?) of black light is the ink most sensitive to? i want to purchase some uv leds and want the brightest florescence i can get. thx** A: 385-390NM. Fluorescent black light works the best. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff is excellent- but truly an ink, not a paint. *by A***R on October 21, 2022* This product is easy to use and looks great under a black light.
